Mechanism Description miR-634 is an important player in cisplatin-resistance. First of all, miR-634 was the only miR miR-634 overexpression in ovarian cancer cell lines and patient samples negatively regulates important cell-cycle genes (CCND1) and Ras-MAPk pathway components (GRB2, ERk2, RSk1 and RSk2). Inhibition of the Ras-MAPk pathway resulted in increased sensitivity to cisplatin, suggesting that the miR-634-mediated repression of this pathway is responsible for the effect of miR-634 on cisplatin resistance.

Mechanism Description miR-634 most significantly downregulated in the paclitaxel-resistant CNE-1/Taxol, in regulating the paclitaxel sensitivity in NPC cells. miR-634 expression in the CNE-1/Taxol cells by lentivirus infection, miR-634 re-sensitized the CNE-1/Taxol cells to paclitaxel in vitro. In xenograft mouse model, miR-634 inhibited tumor growth and (+) paclitaxel sensitivity.
